Application filed December 30, 1922. Serial No. 509,927.

To all whom it may concern: 1

Be it known that I, JULIUs A. LnnDEcKn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Kerosene-Gas Burners, of which the following, when taken in connection with the drawing accompanying and forming a part hereof, is a full and complete specification.

This invention relates to a burner in which kerosene oil is converted into a gas and consumed.

The apparatus embodying the invention being particularly adapted for heating bakers ovens.

Among the objects of the invention is to obtain a burner which will produce from kerosene oil a clean flame, without the use of a wick; a burner which will not produce carbon or soot when in use; a burner which does not require adjustment of the fuel supply relative to the supply of air supporting the combustion obtained thereby; and a burner which is economically made, is durable, not liable to get out of order, and easily controlled.

In the drawing referred to Fig. 1 is a top plan view of a burner embodying the inven-' tion, with a portion of the top wall of the body member of the burner broken away, to disclose passage ways therein.

Fig. 2 is a side elevation of the burner, with a portion thereof in vertical section, on line 22 of Fig. 3, viewed as indicated by arrows, to disclose passage ways in the body member to View.

gig. 3 is a front elevation of the burner; an

F ig. 4 is a section on line 4-4 of Fig. 3, viewed as indicated by arrows.

A reference character applied to designate a given part, indicates said part throughout the several figures of the drawing wherever the same appears.

A represents a body member, preferably of cast metal, which is provided with a large central passage way, (B) extending longitudinally therethrough, being open at both ends; and is provided with the additional passage ways C, C, and C G which extend from one end thereof to near the other end. Said body member is also provided with the passage ways D, D, (indicated by broken lines in Figs. 2 and 3) which connect the respective assage ways C, C, with passage ways C C (2, d, represent screw threaded plugs which are inserted in the ends of passage waysD, D, and by means of which said passage ways are closed at said ends. E, E, represent fuel supply pipes, the discharge ends of which are secured in plugs F, F,respectivelv, (see Fig. 2) said plugs being inserted in and closing the inlet ends of passage ways C, C. G represents a metal rod, one of which is contained in each passage way C, G, fitting loosely therein and resting on the bottom thereof, to obtain a crescent shaped chamber in said passage way, as is well illustrated in Fig. 4. H, H, represent street Ls, which are secured, respectively, in the discharge end of passage ways 0*, C. it represents a T, in the cross member of which the Us H, H, are secured, and I represents an additional T, which is secured to T h by connections J. K represents a cap which is attached to T I by nipple k Cap Kis provided with an aperture, (is), and L represents a spindle which is movable longitudinally and arranged to control the aperture is. 1 represents a handle on spindle L, by means of which it is turned, (it being screw threaded in the ordinary Way) to move it longitudinally. M represents the gland of a stufling box around spindle L.

The operation of the burner is as follows: Body member A is heated, preferably by a wood or charcoal fire, and kerosene oil is supplied to the crescent shaped chamber in passa e ways C, C, through fuel tubes or pipes E. The oil in said crescent shaped chamber is converted into a gas which flows, together with any oil in said chamber which remains in a liquid form, through the passageways D, D, into the passage ways 0, C The body member A being heated throughout the gas flowing into passage ways C C is made into what I term a dry gas, and flows from said passage ways through the Us H, H, into T h, connections J, T I and (needle valve L flows from aperture is, and into passage way B, where it is ignited. The flame obtained in passage way B by said ignition, extends through the length of said passage Way, and from the discharge end thereof, as at N, Fig. 2. The aperture 7:: being of small diameter relative to the diameter of the passage ways C, C, D, D, and C C and of the Ls, Ts, and connections to cap K, considerable pres sure is obtained in said passage Ways and connections, so soon asthe gas flowing from being retracted) aperture is is ignited. Ignition of gas flowing from said aperture in produces a flame which is directed against the inner face of passage way B, and for a considerable distance beyond said passage way in the body member. The shape of the crescent shaped chamber in passage ways (1, C, permits only a small body of oil to be in said chambers, a good and uniform quality of gas is obtained, and a non-carbonizing flame is produced from the burner.

therethrough and open at both its ends, and provided with additional and parallel longitudinally extending passage ways, the

lower ones of said additional passage ways in communication, adjacent to the dischar e ends thereof, with corresponding upper a 20 ditional passage ways adjacent to the inlet ends thereof, rods: loosely contained in the lower ones of said additional passage ways,

and fuel supply pipes arranged to discharge into said lower ones of said additional pas- 25 sage ways, in combination with means com-*- municating with the discharge ends of sald additionalupper passage ways to direct gaseous contents of said passage ways into one of the openends of said central passage 30 way.
